That's what the flashlight is for. Nobody had a problem with it, the dark and light parts are normal. Is it not the brightness of your monitor?
The game refused to let me pick up the flashlight. I tried hitting every button though to no prevail. It wouldn't let me pick it up. Maybe it had something to do with the keyboard. I don't know. I'm running Windows 8. And I don't update this computer, because I don't use internet. Except what my phone provides. So. It's highly outdated. I can't create video games like you all can. Only ever designed characters in Skyrim's Race Menu and used the Creation Kit you get with Sexy Beach Premium Resort. I'm an excellent designer of characters. Just been playing the Skyrim game for as long as it's been out. Probably the longest player of Skyrim in the world. And I probably need a new keyboard. So it's possibly because of that, right there.
